2. Architectural projection
Architectural projection, also known as “architectural light and shadow show” or “holographic interactive” architectural projection, is an interactive imaging technology that combines digital multimedia technology with light and shadow technology.
It uses the surface of the building as a projection medium, and integrates 3D digital animation with wall projection media through projection technology to form a three-dimensional stereoscopic image, so that under the illumination of the light, the wall seems to “come alive” and show a variety of changes.
The characteristics of architectural projection mainly include the following aspects:
- Novel art form:
Architectural projection is a branch of new media art and new digital art that combines digital technology with artistic thinking. It is different from traditional art categories and elevates artistic expression to a new height through scientific and technological means.
The display information is rich in content, and the animation effect is three-dimensional and realistic.
Through the integrated coordination of sound, light, and electricity, a highly creative and artistic picture is created, which subverts the traditional sensory experience and gives people a shocking impact and enjoyment from a visual and psychological perspective.
- Innovative scientific and technological means:
Architectural projection integrates a variety of new media technologies, including multi-screen fusion technology, multi-surface correction technology, virtual reality technology, interactive technology, and other advanced technologies.
The application of these technologies has led to continuous innovation and development in architectural projection technology.
The combination of traditional projection equipment and advanced information technology provides software and hardware support for the realization of architectural projection, making the projection effect more accurate and delicate.
- Unique sensory experience:
Architectural projection combines visual, auditory, and other elements to create virtual physical illusions and a real sensory experience.
The image is projected in a complex three-dimensional space, which is more realistic and three-dimensional, matching the building structure and creating a visual illusion.
At the same time, architectural projection can also use sound, light, electricity and other technologies to create a surround sound effect, which is integrated with local history, culture and human stories to bring a full range of sensory enjoyment to the audience.
- مجموعة واسعة من سيناريوهات التطبيق:
Architectural projection can be applied to the facades of buildings, stage scenes, industrial products, indoor spaces, and other scenes.
Through projection technology, static buildings are awakened, allowing buildings to communicate with people in real life, achieving significant economic and social benefits.
For example, using architectural projection for publicity and display in large-scale events can attract the attention of a large number of audiences; using architectural projection to tell historical stories in tourist attractions can enhance the sense of participation and experience of tourists.

3. LED grille screen vs architectural projection: multi-dimensional comparison
When discussing the comparison between LED grille screen and architectural projection, we can conduct in-depth analysis from several aspects such as visual effects, environmental impact, cost and maintainability, and application limitations.
1). Visual effects:
LED grille screen, with its high brightness and high saturation LED lamp beads, shows extremely high color reproduction and clarity and can present delicate and vivid images and videos.
Its pixel points are densely distributed and support a high-دقة display, making the dynamic effects smooth and realistic.
In contrast, architectural projection can also show rich colors and dynamic effects, but its color reproduction and clarity may be affected by the projection equipment, light source quality, and ambient light, and there is a certain deviation.
2). Environmental impact:
The high brightness of the LED grille screen may cause light pollution in some cases, so it is necessary to reasonably control its brightness and irradiation range.
At the same time, its visual effect will also be affected by the surrounding light, especially in a strong light environment; the display effect may be weakened.
Architectural projection, with its soft light changes, has little impact on the surrounding environment, but when choosing the projection location, factors such as wall material, color, and ambient light need to be considered to ensure the best projection effect.
3). From the perspective of cost and maintainability:
The initial investment cost of an LED grille screen is relatively high, including equipment purchase, installation and construction, commissioning, and operation. However, its long-term maintenance cost is relatively stable, and as long as it is regularly maintained and maintained, it can maintain a good use state.
However, it should be noted that some maintenance work on LED grille screens may require high-altitude operations, which increases the difficulty and cost of maintenance.
In contrast, the initial investment cost of architectural projection is relatively low, but in the long-term operation process, it may be necessary to consider the maintenance cost of rental fees or equipment aging.
In addition, the maintenance of architectural projection is relatively simple, mainly focusing on the cleaning, dust prevention, and light source replacement of projection equipment.
4). In terms of application restrictions:
LED grille screen is more flexible in shape, size, and application scenarios. It can be customized according to actual needs to adapt to different architectural styles and decoration needs.
Whether it is الإعلانات التجارية, cultural and artistic المعارض, or urban lighting projects, LED grille screens can show their unique charm. Architectural projection is more suitable for art displays in specific scenes, such as temporary exhibitions and festivals.
Its shape and size are limited by projection equipment and walls, so these factors need to be considered when choosing application scenarios.
